MAGAZINE FOR FIREARMS.

Specification of Letters Patent.

Patented July 27, 1915.

Application filed December 21, 1914. Serial No. 878,245.

employing compressed air as the power agent.

The object of the invention is the improvement in devices of this character; and it consists in certain novel features of construction, as will be hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal vertical section of a portion of an air-gun embodying the present invention. Fig. 2 is a similar view of the projectile-feed devices and the parts associated therewith, shown detached. Fig. 3 is a like view of the magazine-with the rts shown in Fig.2 omitted. Fig. 4 is a fiagmentary plan view of parts shown in Fig. 3.

The reference numeral 5 designates a rotary breech-block mounted in a casing 6 to which the gun-barrel 7 is connected. Said breech-block is provided with a duct 8 which is movable with the block from its full-line position to that in which it is indicated by broken lines 8 in Fig; 1. When in such fullline position, the duct 8 affords communication by a passage 9 with a compressed-air reservoir 10.

11 represents a controllin valve which is yieldinglyheld on its seat y a spring 11 and is moved from its seat by a hammerblock (not shown) striking a firing pin 12 when a quantity of compressed air is to be released for expelling a projectile, as P from the breech-block.

The above-described parts are substantially similar to those illustrated and described in a patent application, Serial No. 874,668, filed by me in the UnitedStates Patent Office November 30, 1914.

According to the present invention, I provide a magazine which, as illustrated, extends through the air-reservoirv and seats in the casing 6. The magazine is comprised of concentrically arranged outer and inner tubular casings or shells 13 and 14 (Figs. 1 and 3) which extend from the bore of the casing 6 to a distance outside of the rear wall 15 of said reservoir. Both ends of the inner shell are open except for the abutment afforded by the breech-block when the same is in the position shown in Fig. 1, but the space between the two shells is at the forward end closed by a ring-piece A.

The inner diameter of the shell 14 is slightly greater than the diameters of the projectiles which are denoted by P. Provided for the outer ends of said shells is a closure 16 formed preferably in the shape of a knob. Secured to this closure is a tube 17, Fig. 2, which is adapted to be inserted, as shown in Fig. 1, in the annular interstice between the shells 13 and 14. The tube 17 serves as a casing for the projectile-feeding devices when the same are withdrawn from the magazine and also serves, with the shelltubes 13 and 14, to guide the referred to feeding devices when being introduced into the inner tube 14. Rigid with the tube 17 is a stud 18 which serves as a latch in an angular shaped slot 19 in the shell 13, Fig. 4, whereby the tube 17 is detachablyconnected by a bayonet joint with the magazine. Interiorly of the tube 17 is a projectile follower 20 of a diameter to fit loosely within the magazine-tube 14. This follower is secured to an end of a wire 21 which fits telescopically into a tube 22 which, in like manner, fits into a second tube 23 which is secured to the closure 16. The rear ends of the closure 16 and the follower 20 to urge the latter forward for feeding the projectiles into the breech-block.

To load-the magazine, the plug 16 together with the tube 17 and the springpressed telescopic devices, are withdrawn from the magazine, and the projectiles are inserted in the inner shell 14. The follower 20 is then introduced into the shell 14 and the tube 17 into the annular space bctween the shells 13 and 14. By pushing against the head or closure 16 the tube 17 is further moved into said space until the stud 18 is caught in the circumferential directed portion of the slot 19. As the tube -17 is thus introduced, the follower 20 will engage the rearmost rojectile, and thereby cause the other projectiles in the magazine to be pushed forward until arrested by the fore- I most one and stopped by the breech-block, and thereafter the spring 2 1 will be compressed as the' several telescopic members 21,

1'22 and 23 close up with respect to each other.- The magazlne being thus charged, the spring will serve to ress the projectiles forward, sothat when t e "cavity or duct 8 'of the breech-block.is'presented to the magazine the foremost of the projectiles in the I latter will be deposited in such cavity. The

projectiles will in thisway be successively delivered to the breech-block until they are all gone, whereupon the follower will 'be prevented from any further forward travel by the various shoulders and collars of said telescopic members being engaged. This is an important function,-inasmuch as the follower 20 is restrained from entering the cavity of the breech-block with a liability of causing the same to become jambed or otherwise deranged. I

I have illustrated the so-called telescopic device's-as being comprised of a wire-memher 21 and two tube members 22 and 23, but

it is obvious that more or less such members tacle, a follower within the shell, adetachand headwith said shell...

able closure for an end of the shell, a spring tending to push the follower away from said head and telescopic devices connecting the head and said follower whereby the travelof the latter with limited. e

2. In a magazine of the class described, a

respectto the head is casing shell serving as a projectile receptacle, a follower adapted to be inserted within said shell, a head, extensible means connecting said head with said follower, a

spring mterposed'between said head and the follower, a tube secured to the head and adapted to receive the shell therein, and

means for detachably coupling said i tube of the casing.

3. Ina magazine of the class described, a 5

casing shell open at both ends, a head, a follimiting the separation thereof, a spring tending to push'the follower away from the v head, and means for removably securing the head at the'outer end of said shell. 4. In a magazine of the class described, a casing shell open at both ends, a head, a follower insertible within said shell, means connecting the head with said follower to limit the travel of the latter from the head, a spring tending to push the, follower away from the head, and means for removably securing the head at the outer end of said shell. J

5. A magazine for fire-arms, comprising a casing formed of two concentrically-arranged shell elements, the inner of said elements being open at both ends and the other element at the rear end only, a head for closing the rearend of said casing, a follower adapted to be inserted within the inner of said elements, a sprin interposed between said head and the ollower for pushing the latter forwardly, means connected to the head for limiting the forward travel of said follower and means for detachably securing said head to the rear end 6. A magazine for fire-arms, comprising a casing formed of two concentrically arranged shell elements, the inner of said elements being open at both ends and the other element at the rear end only, a head for closing the rear end of said casing, a tube.

connected to said head and adapted to be inserted in the annular space intermediate said casing elements, a follower adapted to be inserted within the inner of said elements, a spring interposed between said head and the follower for pushing the latter forwardly, means connected to the head 7 for limiting the forward travel of said fol- 100 lower, and means for detachably securing said head to the rear end of the casing.
